I’m trying to install cert-issuer on a fresh installation of Ubuntu 18.04.1
So i run the command “python3 setup.py experimental --blockchain=ethereum” and the installation stopped with an error same as the below picture but with coincurve instead of requests[security].

Then i immediately run the same command again and get a different error this time (see below picture)

Apparently if running sudo python3 setup.py experimental --blockchain=ethereum outside of virtulenv instead of python3 setup.py experimental --blockchain=ethereum i don’t get any errors. But then again when running cert-issuer -c conf.ini i get the same error as virtualenv (AttributeError: ‘tuple’ object has no attribute ‘unsigned_cert_file_name’).
